From the whole daylight/darkness bit in Alaska, I sometimes can't sleep for days, then crash hard for about 2 whole days... It's rare now.
However, there is a medical condition, where people can't sleep for years (can't recall the exact name, it was a Trivial Pursuit question the other
day...)



so how long do you think i can do it for, ive not had sleep for 19 hours which is not bad im not at all tired
